NEXT GENERATION B-FACTORIES

The KEKB and PEP-II B factories have achieved world record luminosities while doubling or tripling their original design luminosities. The demand now from the physics community is for Super B Factories with orders of magnitude higher luminosities than those achieved by the present generation of machines. The next-generation B factories, which aim to push back the luminosity frontier in the search for physics beyond the Standard Model, are reviewed in this report.
